CLARENCE J. GRAHAM AND JOSEPH A. FARRIS, OF CHICAGO, ILLINOIS.

PIPE.

To all whom it may concern:

Be it known that we, CLARENCE J. GRA- HAM and Josnrn A. FARRIS, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inPipes; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The primary object of this invention is to provide an attachment, forsmoking pipes, that will purify the smoke before the same passes fromthe bowl of the pipe to the stem thereof.

Another object of the invention is to provide a smoke purifyingattachment, for smoking pipes, that can be associated with any style ofpipes, can be cheaply manufactured, will be durable and eflicient inoperation.

Other objects will appear and be better understood from that embodimentof our invention of which the following is a specification, referencebeing had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a vertical sectional view taken through the bowl of a pipe,and through the attachment, and showing the manner of mounting theattachment within the pipe,

Fig. 2 is a top plan view of the bowl of the pipe.

Referring to the drawing more in detail, the letter A designates thebowl of a smoking pipe, and B the stem thereof. In this instance, thebottom wall of the bowl is provided with an internal annular flange C.

The smoke purifying attachment for the pipe consists of a cylindricalshaped receptacle 1, the lower end of which is received within theannular flange C, while the upper end of the receptacle is closed bymeans of a removable cap 2, the said cap 2 being provided,concentrically, with an opening 3, and is also provided eccentricallywith an opening 4:. The diameter and the height of the cylindricalreceptacle 1 are considerably less than the diameter and height of thebowl A, as is shown in Fig. 1 of the drawing. Removably fitted withinthe open end of the bowl A, is an inverted conical shaped auxiliary bowl5, the said bowl having its larger end provided with an annular flange6, which overlies the upper end of the walls-of Specification of LettersPatent.

Serial No. 66,773.

the bowl A and serves to provide an airtight joint between the auxiliarybowl and the bowl A. The smaller or apex end of the bowl 5 has a passage7 therein, which establishes communication between the interior of theauxiliary bowl 5 and the main bowl and is alined with the opening 3 inthe cover 2 for the receptacle 1.

A conical shaped screen 8 is fitted within the auxiliary bowl 5 and islocated at the smaller end of the bowl 5, and a vertical metallic tube 9has one end extending through the passage 7 in the smaller end of thebowl 5, and its opposite end extending through the opening 3 in thecover 2 for the receptacle 1 and into the .reccptacle and is terminallyspaced from the bottom wall of the receptacle 1, as shownin Fig. 1 ofthe drawmg. 1

An outlet pipe 10, which is of a length considerably less than thelength of the tube 9, has one end fitted within the opening 4, in thecap 2, and extended within the receptacle, and the upper end of the pipe10 is curved laterally, as shown at 11, and has the bore thereoflocated, approximately in line with the bore of the pipe stem B.

In use, the receptacle 1 is partly filled with water, or other purifyingliquid, and placed within the bowl A of the pipe, as shown in Fig. 1,and one end of the tube 9 extended through the opening 3 in the cap orcover 2 for the receptacle 1, and the upper end of the tube is snuglyreceived by the passages 7 in the smaller end of the auxiliary bowl 5.The auxiliary pipe 5 is then filled with tobacco, and a draft producedthrough the stem B, in the ordinary manner, so as to admit of thetobacco being lighted in the usual manner. By virtue of the draftcreated through the pipe stem B, the smoke will pass from the auxiliarybowl 5, downward through the tube 9 and into the receptacle 1, and thenup through the water or other liquid in the receptacle 1 and out throughthe outlet pipe 10 to the interior of the bowl A, and then be conveyedthrough the bore of the pipe stem.

By virtue of the passage of the smoke through the water, or otherliquid, the same will be purified and also cooled, before reaching themouth of the smoker.

From the foregoing description, taken in connection with theaccompanying drawing, it will be seen that we have provided a smokepurifying attachment that can be applied to any type of pipe and whichwill ell'ectively purify and cool the smoke before the same enters themouth of the smoker; also an attachment that can be easily,and'conveniently removed from the pipe bowl and cleaned so as to berendered sanitary and assure of the maximum purification of the smokebefore the same enters the mouth of the smoker.

Having thus described our invention What we claim as new, is:

The combination with the bowl and the stem of a smoking pipe, of anauxiliary bowl fitted within the main bowl and having a passage in thelower end thereof, a liquid holding receptacle detachably positionedwithin the main bowl and underlying the auxiliary bowl, an inlet pipehaving one end extending into the passage in the auxiliary bowl andhaving its opposite end extending into the receptacle and having theterminal of the last-mentioned end located adjacent the lower wall ofthe liquid holding receptacle, an outlet pipe located within the mainbowl of the pipe and having one end communicating with the interior ofthe receptacle and its opposite end positioned in line with the bore ofthe pipe stem, and means carried by the lower wall of the main bowl ofthe pipe and engaging the liquid holding receptacle for holding thelatter against movement.

In testimony whereof we al'fix our signatures in presence of twowitnesses.
